Heavy-Duty Transmission Pumps: High-Pressure Solutions for Smooth Shifting

If your heavy equipment is experiencing delayed gear engagement or overheating, a failing replacement transmission pump is often the root cause. As the primary source of hydraulic flow within the gearbox, the transmission oil pump must maintain precise pressure to ensure clutch packs engage without slipping. BeeSpareParts offers a range of precision-machined transmission pumps—including gear-driven and internal lobe designs—engineered to restore factory-spec hydraulic performance to your drivetrain.

A loss of transmission pressure can quickly lead to burnt and catastrophic gear damage. To protect your new pump, we strongly recommend replacing your and flushing the lines to remove any metallic debris. Our transmission pumps are direct-fit alternatives that use high-strength alloy housings and hardened rotors to resist wear and cavitation, even under continuous heavy-load operations.

Whether you need a charge pump for a JCB backhoe, a transmission pump for a CAT wheel loader, or a Volvo dumper oil pump, our parts are factory-tested for flow rate and pressure stability. Restore your machine’s pushing power—order your premium transmission pump solution today.

Fits for:

  • Major Brands: Caterpillar (CAT), JCB, Komatsu, Volvo, Dana, Spicer.

  • Common Issues Solved: Low transmission pressure, harsh shifting, pump cavitation noise, and overheating.
